A PhD candidate in Remote Sensing in the Ethiopian Space Science and Technology Institute (ESSTI).
How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Global Ecosystem Dynamics Investigation (GEDI); a full waveform lidar sensor, acquires samples of the terrain and vegetation structures. To derive a spatially continuous estimate, the canopy height and cover metrics retrieved from GEDI L2A and L2B, respectively, were extrapolated using support vector regression models and explanatory variables deri...
Ecosystem extent is one of the essential biodiversity variables under the class of ecosystem structure. Due to the scarcity of all elements of an ecosystem, landcover is often used as a proxy though it constitutes only one aspect of it. When landcover is used as a proxy, ecosystem extent and its dynamics can be monitored using remotely sensed datas...
Global environmental changes have implications for the terrestrial ecosystem functioning, but disentangling individual effects remains elusive. The impact of vegetation responses to increasing atmospheric CO2 concentrations is particularly poorly understood. As the atmospheric CO2 concentration increases, the CO2 acts as a fertilizer for plant grow...
Due to the rising demands of fuels combined with efforts in reducing greenhouse gas emission, countries all over the world are looking for alternative clean energy sources such as biofuel. Ethiopia imports a huge amount of fuel each year and to supplement its energy needs efforts are underway for biofuel development. Despite this, comprehensive ass...
Vegetation phenology is an integrative environmental indicator of climate change and long-term observations of the changes in plant phenology using remote sensing technologies help us to understand climate change trends over space and time. However, such trends and their implications for ecosystem health have been poorly explored in Ethiopia. In th...
